Ultrasound uses sound waves to create images of the internal organs on a screen, without radiation. Standard 2D ultrasound gives black-and-white cross-sectional images, while 3D ultrasound builds detailed three-dimensional pictures. It is the most important first-line imaging test in infertility.
What ultrasound shows
For the uterus, ultrasound detects polyps, fibroids and adhesions in the cavity, congenital anomalies and the size of the uterus. It also measures the thickness and pattern of the lining (endometrium), which is especially useful during ovulation treatment or when the lining grows poorly.
For the ovaries, it helps diagnose polycystic ovaries, functional cysts (follicles that have grown larger than normal), other cysts, a blood-filled corpus luteum cyst, and endometriomas (“chocolate cysts”). An antral follicle count early in the cycle estimates ovarian reserve. During ovulation treatment, it tracks the growing follicles: each appears as a dark, round structure in the ovary that grows by about 1.5–2 mm a day. When it disappears or collapses, ovulation has occurred, and a little fluid may be seen behind the uterus.
Types of pelvic ultrasound
Transabdominal ultrasound
The probe is moved over the lower abdomen. A full bladder is needed to obtain clear images. It is used mainly when a vaginal scan is not suitable.
Transvaginal ultrasound
A slim probe is inserted gently into the vagina. Because it is much closer to the uterus and ovaries, it gives far clearer images and more accurate measurements, and it is the standard method in fertility care. It does not require a full bladder.
3D ultrasound
Advanced machines build three-dimensional images, which are particularly accurate for assessing the shape of the uterine cavity and diagnosing congenital anomalies such as a septum.
Doppler ultrasound
Doppler measures blood flow in vessels, such as to the uterus, the lining, the ovaries and the follicles. It helps assess fibroids, polyps and ovarian cysts, though its value in predicting treatment success is limited.
Saline sonography (SIS)
Sterile saline is introduced into the uterus through a thin catheter during a vaginal scan, outlining the cavity clearly to detect polyps, fibroids and adhesions.
